Constraints

• Apply @rules/laravel/filament.mdc — for custom Blade + Tailwind, create and register a custom theme; use Filament\Support\Icons\Heroicon for icons.
• Apply @rules/laravel/livewire.mdc — keep Blade templates presentation-only; components are slim entry points.
• Apply @rules/laravel/architecture.mdc and @rules/laravel/laravel.mdc for file placement.
• Apply @rules/security/frontend.md if any audit fix touches output rendering or CSP.
• Stack is Blade + Livewire + Alpine.js + Filament + Tailwind. No React/Vue/Next.
• Any live-URL or browser-screenshot step is OPTIONAL and tool-agnostic — never a hard dependency.

Use when

• Starting a project that needs a coherent design system.
• Auditing an existing codebase for visual consistency.
• Before a redesign — to understand what already exists.
• The UI looks "off" but the cause is unclear.
• Reviewing a PR that touches styling, Tailwind config, or a Filament theme.

This skill has three modes. Pick the one that matches the request.

---

Mode 1: Generate a design system

Produce a documented token set wired into Tailwind, a Filament theme, and reusable Blade/Livewire components.

Steps

1. Scan existing styling for de-facto patterns: tailwind.config.js, resources/css/app.css, Blade views under resources/views, and any Filament theme CSS. Collect every color, font, size, radius, and shadow already in use.
2. Extract tokens into these groups: colors (brand, neutral, semantic success/warning/danger/info), typography (font families, type scale, weights, line heights), spacing scale, border radius, shadows, breakpoints, z-index layers.
3. Inspiration (optional) — if a browser tool is available you may reference real sites; never depend on it. Tokens must be derivable from the codebase alone.
4. Define tokens in Tailwind config plus CSS custom properties so values stay coherent across light/dark and component states.
5. Theme Filament — register a custom panel theme that consumes the same variables.
6. Build reusable components as anonymous Blade components (and Livewire components where interactive state is needed) that consume the tokens — never hard-coded hex.
7. Document decisions and rationale in DESIGN.md.

Tailwind tokens + CSS variables

// tailwind.config.js
export default {
  theme: {
    extend: {
      colors: {
        brand: { DEFAULT: 'rgb(var(--c-brand) / <alpha-value>)' },
        surface: 'rgb(var(--c-surface) / <alpha-value>)',
        danger: 'rgb(var(--c-danger) / <alpha-value>)',
      },
      borderRadius: { card: 'var(--radius-card)' },
      boxShadow: { card: 'var(--shadow-card)' },
    },
  },
};

/* resources/css/app.css */
:root {
  --c-brand: 37 99 235;      /* single source of truth */
  --c-surface: 255 255 255;
  --c-danger: 220 38 38;
  --radius-card: 0.5rem;
  --shadow-card: 0 1px 2px rgb(0 0 0 / 0.06);
}
.dark {
  --c-surface: 17 24 39;
}

Reusable Blade component

{{-- resources/views/components/ui/card.blade.php (anonymous) --}}
@props(['variant' => 'default'])
<div {{ $attributes->class([
    'rounded-card shadow-card bg-surface',
    'border border-gray-200 dark:border-gray-700' => $variant === 'outlined',
]) }}>
    {{ $slot }}
</div>

Use <x-ui.card>…</x-ui.card> everywhere instead of repeating utility strings. For interactive widgets, wrap state in a Livewire or Alpine component but keep the visual shell in the shared Blade component.

Filament theme

/* resources/css/filament/admin/theme.css */
@import '/vendor/filament/filament/resources/css/theme.css';
@import '../../app.css'; /* reuse the same --c-* variables */

Register it on the panel provider with ->viteTheme(...) so Filament and the public UI share one token set.

Output: DESIGN.md (token tables + rationale), updated tailwind.config.js, CSS variables in app.css, the Filament theme, and the shared Blade/Livewire components.

Mode 2: Visual audit

Score the UI across 10 dimensions, 0–10 each. Every dimension needs a score, a concrete file:line example, and a fix.

1. Color consistency — palette tokens vs ad-hoc hex/rgb() strings in Blade.
2. Typographic hierarchy — clear h1 > h2 > h3 > body > caption; no skipped levels.
3. Spacing rhythm — a consistent scale (4/8/16) vs arbitrary mt-[13px].
4. Component consistency — similar elements built from the same <x-ui.*> component.
5. Responsive behavior — fluid across breakpoints; no overflow or layout breaks.
6. Dark mode — complete dark: coverage, not half-applied.
7. Motion — purposeful Alpine/transition use vs gratuitous animation.
8. Accessibility / contrast — token contrast ratios, visible focus states, touch targets (cross-link frontend-a11y).
9. Information density — clean and scannable vs cluttered.
10. Polish — hover, transition, loading (wire:loading), and empty states present.

A live-URL crawl or screenshot pass is OPTIONAL. If no browser tool exists, audit from the Blade/Tailwind source and Filament config directly — that is sufficient.

Report format per dimension:

Color consistency — 6/10
  resources/views/livewire/dashboard.blade.php:42 — bg-[#3b82f6] bypasses the brand token
  Fix: replace with bg-brand and add the token if missing

Mode 3: AI-slop detection

Flag generic AI-generated design tells and propose a deliberate alternative:

• Gratuitous gradients on every surface.
• Purple-to-blue default gradients with no brand basis.
• Glassmorphism / backdrop-blur cards with no functional purpose.
• Rounded corners on elements that should be square (tables, inputs in dense UIs).
• Excessive scroll-triggered animation.
• Generic centered-hero over a stock atmospheric gradient.
• A personality-free sans stack that ignores the product domain.

For each hit, give file:line and a concrete fix that ties back to the project tokens and the chosen design direction (cross-link frontend-design-direction).

Done when

• (Generate) Tokens live in Tailwind config + CSS variables, the Filament theme consumes them, shared Blade/Livewire components replace duplicated utility strings, and DESIGN.md documents the rationale.
• (Audit) All 10 dimensions scored, each with a file:line example and a fix.
• (Slop) Every flagged pattern has a location and a deliberate replacement.
• No hard-coded colors remain where a token exists; no React/Vue artifacts introduced.

Output Humanization

• Use blader/humanizer for all skill outputs to keep the text natural and human-friendly.
